Task: Calculate the number of paper cranes made by Natasha in the last day.

To calculate the number of paper cranes made by Natasha in the last day, we need to determine the pattern of increase in the number of cranes she makes each day.

According to the information given, Natasha made 6 cranes on the first day. We also know that she makes an increasing number of cranes each day compared to the previous day.

To find the total number of cranes made by Natasha in 15 days, we can use the formula for the sum of an arithmetic series:

Sum = (n/2)(first term + last term)

Where: - n is the number of terms in the series (in this case, 15) - first term is the number of cranes made on the first day (6) - last term is the number of cranes made on the last day

To find the last term, we need to determine the common difference between each day's production of cranes.

Unfortunately, the search results provided by You.com do not contain the necessary information to determine the common difference or the last term. Therefore, we are unable to calculate the exact number of cranes made by Natasha on the last day.

To solve this problem, we need additional information about the pattern of increase in the number of cranes made by Natasha each day.
